The invention provides a detection method and a detection tool for a control arm bulb position. The detection method for the control arm bulb position comprises the following steps that: decomposing the bulb spatial position of the control arm bulb into a vertical direction position and a horizontal direction position, and independently measuring the vertical direction position and the horizontaldirection position to determine the bulb spatial position of the control arm bulb. The detection tool for the control arm bulb position comprises a bottom plate, a positioning position, a clamping device and a measurement device, wherein the positioning device and the measurement device are independently fixed on the bottom plate, the clamping device is fixed on the positioning device, the controlarm assembly is fixed and positioned through the positioning device and the clamping device, and the measurement device is used for measuring the sphere center position of the control arm bulb. By use of the detection method, through the direct measurement of a feeler gauge and a dialgage, the practical position of the sphere center is obtained, the sphere center position of the bulb can be accurately and quantitatively detected, the reliability of a product is improved, and a convenient condition is provided for subsequent quality improvement.
Description
technical field [0001] The invention relates to the field of position detecting methods, in particular to a method for detecting the position of a ball head of a control arm and a checking tool thereof. Background technique [0002] In the suspension structure of automobile chassis, the control arm is an important part. figure 1 It is a structural schematic diagram of the control arm assembly in the prior art. Such as figure 1 As shown, the control arm 10 includes a ball joint assembly 11 , a front bushing assembly 12 connected to the vehicle body, a rear bushing assembly 13 and a control arm body 14 . [0003] figure 2 It is a structural schematic diagram of a ball head assembly in the prior art. Such as figure 2 As shown, the common ball head assembly 11 includes a ball stud pin 111, a dust cover 112 and a ball head seat 113, figure 2 The reference numeral 114 is the center position of the ball head. [0004] In actual use, the ball joint assembly 11 of the contr...
